Vad gör folk hela dagarna?

"Vad gör folk hela dagarna" av Richard Scarry kom 1968. I den beskrivs vad folk gör från morgonen till kvällen.

Vad gör du folk 2014. Det mesta är troligen samma sak men nu finns smarta telefoner och Internet vilket gör att det finns andra saker att göra. Med hjälp av Aviate för Android har Yahoo sammanställt infografik om vad gör med sina mobiler.

Women in science that should be more famous

On August 13, the first woman, Maryam Mirzakhani, received the Field Medal for outstanding work in mathematics. There have been many women who have contributed to science but are rarely known as Einstein, Newton or Gallieo. The films explain what the women have contributed to:

Grace Hopper

Scientists are not often invited to American talk shows

Grace Hopper  - invented the first compiler, which today, for example, makes Java into language so the computer understands, pedagogically explains how long a nanosecond is

Ada Lovelace

A brief review of Ada Lovelace's contribution to science. According to many, she wrote the first computer program over 100 years before the first computer was manufactured.

Hedy Lamarr

In addition to being a Hollywood star in Hollywood, in 1942, along with George Antheil , she created an automatic frequency switching system that would make it impossible for the enemy to disturb torpedoes. The system was first used in 1962. Their idea became the basis for technologies such as Bluetooth.

Hypatia (350 fKr – 370 fKr)

This clip is from the movie Agora. The sequence above is fictitious but she was a good mathematician. The first female mathematician whose life is documented.

Emmy Noether

Einstein called her the most important woman in the history of mathematics. In the film you explain why. In short, it can be said that there are symmetries in physics that correspond to a physical preservation layer such as the law on the conservation of energy, the conservation of the amount of movement.

The list can be made longer and I have missed someone obvious so write in the comments. I finish with the super hero number one. The reason why she can be compared to a superhero comes at the end of the movie

Marie Curie

Only four people have received the Nobel Prize twice. Marie is one of these. First time for research on radioactivity and the second time for the discovery of the elements radium and polonium. She died of aplastic anemia in 1934, probably a result of the ionizing radiation she was exposed to in her laboratory. Her notes (and even her cookbooks) from the 1890s are considered too dangerous to handle because of their radiation content, and are stored in lead-lined boxes. Anyone who wants to read them must wear protective clothing.

Caroline Herschel

She was the first woman to receive a salary for her contribution to science, which received the Royal Astronomical Society's gold medal (1828) and was named honorary member of the Royal Astronomical Society (1835) along with Mary Somerville. In addition, she was appointed in 1838 as an honorary member of the Royal Irish Academy. Prussian King Frederick William IV gave her a gold medal for scientific research on her 96th birthday in 1846

Botten Ada gör förutsägelser om riksdagsvalet 2014

Det har funnits opinionsundersökningar sedan länge i Sverige. Något vi inte sätt mycket av är förutsägelser av valresultatet som baseras på dessa opinionsundersökningar. Botten Ada är ett exempel på hur statistiker försöker "gissa" hur det går i valet. I SvD skriver de att Ada redan kan ha räknat ut valresultatet. Med tanke på hur många det är som bestämmer sig sent kanske det är svårare än någonsin att förutsäga resultatet.
Man kan göra egna jämförelser på Botten Adas webbplats

Poll of polls är en webbsida där en annan statistiker sammanställer de olika opinionsinstitutens mätningar.
